Energy-saving and environment-friendly door and window sealing rubber strip and preparation method thereof

Abstract

The invention discloses an energy-saving and environment-friendly door and window sealing rubber strip and a preparation method thereof and relates to the technical field of energy-saving materials. The sealing rubber strip is prepared from the following raw materials: modified terpene resin, methyl acrylate, powder nitrile butadiene rubber, activated attapulgite clay, composite enhanced fibers, zinc stearate, sodium metasilicate, sodium dodecyl sulfate, diphenyl phosphate, dimethyl sulfoxide, hindered phenol, an anti-radiation agent, a crosslinking agent and a plasticizer. The preparation method of the energy-saving and environment-friendly door and window sealing rubber strip comprises the steps of mixing, extruding the raw materials and the like. The sealing rubber strip disclosed by the invention is simple and convenient to operate and low in production cost, has excellent mechanical strength, fireproof and flame-retarding performance, heat-insulation and sound-blocking performance, and corrosion-resisting and ageing-resisting performance; the sealing rubber strip is widely applied and the utilization performance and the service life are greatly improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving materials, in particular to an energy-saving and environment-friendly door and window sealing strip and a preparation method thereof. Background technique [0002] Door and window sealant strip is a type of seal mainly used in plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decoration doors and windows. Plastic steel door and window seal strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer seals, silica gel and other materials. [0003] In the production process of building decoration doors and windows, the input cost of sealing strips is relatively small, but its role cannot be ignored. The key to the structure of doors and windows lies in its sealing, and the sealing strips play a pivotal role; the sealing strips in the existing market The material of the strip is generally PVC modified, rub...

Problems solved by technology

[0003] In the production process of building decoration doors and windows, the input cost of sealing strips is relatively small, but its role cannot be ignored. The key to the structure of doors and windows lies in its sealing, and the sealing strips play a pivotal role; the sealing strips in the existing market The material of the strip is generally PVC modified, rubber, fiber, and fluff. The small molecule plasticizer in the modified PVC is easy to migrate to the surface of the product, resulting in poor elasticity of the sealing strip and hardening of the material, thus affecting The sealing performance of doors and windows; rubber sealing strips have the disadvantages of high energy consumption and heavy pollution in the rubber production process. After being used as sealing strips, some small molecule additives also have strong mobility and lead to elasticity. Defects such as deterioration, and are more harmful to the human body. At present, EPDM (ethylene-propylene-diene rubber) sealing strips are more commonly used in rubber, although EPDM itself has good heat resistance, chemical resistance, and water resistance. However, as an organic polymer material, it will gradually deteriorate in physical and mechanical properties due to the combined effects of external environmental factors (such as light, heat, oxygen and corrosive media, etc.) during use, until it eventually loses Use value, on the surface, it is characterized by cracking, stickiness, hardening, softening, powdering, discoloration and mildew, which will bring great inconvenience to people's normal life and office

However, the existing sealing strips of medium fiber and fluff are easy to absorb dust, have low strength, low elasticity, and poor sealing performance. Therefore, developing a door and window sealing strip that can overcome the above defects has become a technical problem to be solved urgently by those skilled in the art.
